In one of the thatched huts he made a comfortable bed of palm leaves. They seemed to retain the heat of the day. When Adam lay down to go to sleep he experienced a vague, inexplicable sense that the very strangeness of the present circumstance was familiar to him. But he could not hold the sensation, so did not understand it. He was very tired and very sleepy, and there was an uncomfortable empty feeling within him. He looked out and listened, slowly aware of a great, soft, silent black enveloping of his environment by the desert night. There seemed to be an aloofness in the immensity of this approach and insulation--a nature that, once comprehended, would be appalling. This thought just flashed by. His mind seemed concerned with something between worry and fear which persisted till he fell asleep. In the dim, gray dawn he awoke and realized that it was hunger which had awakened him. And he stole out on his imperative quest. He did not see the sunrise nor the broadening day. His instinct was to hunt. Doves and blackbirds visited the stream, and a covey of desert quail seemed tame; but, owing to overeagerness and clumsiness, he did not succeed in killing a single one. He followed them from place to place, all over the oasis, until he lost sight of them. He baited his two traps with cactus fruit and set them, and he prowled into every nook and cranny of the canyon oasis. Lizards, rattlesnakes, rats, ground squirrels rustled from his stealthy steps. It amazed him how wary they were. He might have caught the rattlesnakes, but the idea of eating them was repugnant and impossible to him. The day passed more swiftly than had yesterday. Its close found him so tired he could scarcely stand, and with gnawing hunger growing worse. The moment he lay down sleep claimed him. Next day he had more and better opportunities to secure meat, but he failed through haste and poor judgment and inaccuracy. His lessons were severe and they taught him the stern need of perfection. That day he saw a hawk poise high over a spot, dart down swiftly, to rise with a squealing rat in its claws. Again he saw a shrike, marked dull gray and black, sail down from a tree, fly very low along an open space of ground to avoid detection, and pounce upon a lizard. Likewise he saw a horned toad shoot out an extraordinarily long and almost invisible tongue, to snatch a bee from a flower. In these actions Adam divined his first proof of the perfection of desert hunters. They did not fail. But he was not thus equipped.
